What is DevOps? a thread...

1. World Before DevOps - Development & Operations team, work in isolation from each other. - Development team performs - Designing, Development, and Testing of the Software. - At the end of the cycle, the Development team delivers the executable deliverables.

- This package needs to be deployed on the servers so that end-user can start using our software. - Operations team, takes this package & deploys onto the servers. - Ops team also - Maintains, Scales, Secure the Application, Take Backups & Client Feedback, etc.

2. The Problem - With less knowledge about the software, if there is any issue during deployment then the Operations team need to go back to Dev team. - Many-a-times, it wastes more time, and ultimately the customer suffers.

- There is little or almost no communication between Dev and Ops team due to which they don't understand each other's roles well. - Most of the time they blame each other for any delays and miss-happenings.

- Increases time to market, because deployment happens less frequent due to which any important feedback from customer takes time to reach to the customer. - Most of the deployment work is managed manually, hence it takes more human hours to do routine work.

- To solve all the above problems, DevOps is found as solution. - Let's understand what is DevOps.

3. DevOps - In simple terms, DevOps = Development + Operations - It's a cultural shift, in which Dev & Operations teams are mixed together and made into one team. - They work more collaboratively toward a single goal and shared responsibility.

- Most of the stages between development to deployment are automated through the process of CI/CD pipelines. - This enables developers with little exposure to Operations work to make regular deployments. - Whenever they need, Operations team helps them as they work closely.

- When something is developed, it is instantly merged, build and deployed onto the servers via CI/CD. Ready for testing and customer review. - All cloud providers provide good support to modern DevOps tools, which made this possible.

4. Benefits of DevOps: - Faster time to market. - Increase productivity, as most of the parts are automated team focuses more on innovation and improvement. - Continuous feedback loop from customers keeps running hence improving the software quality.
